5. AVL Tree Insertion(240) AVL Tree Insertion Overview AVL tree is a special binary search tree, by definition, any node, its left tree height and right tree height difference is not more than 1. The purpose of AVL tree is to try best to reduce the search time complexity. if the bina...
1 inclusively. The Height of any node is determined by the difference of the level of height of left sub-tree and right sub-tree. AVL keeps track of height of every node and it updates after every insertion.
这里的树节点没有指向父节点的指针,因此往树中插入节点的过程中需要压栈,以在插入完成后进行回溯。 typedefstructTreeNode*Tree;structTreeNode{Tree left;// 左子树Tree right;// 右子树intheight;// 节点所在高度,平衡因子靠这个算intval;// 节点值}; 失衡类型 - LL型失衡# LL型字面展开来看就是Left-Left。
After deletion, retrace the path back up the tree (parent of the replacement) to the root, adjusting the balance factors as needed. 下面先来分析下不平衡发生的四种情况: 1、An insertion into the left subtree of the left child of A; (LL) 2、An insertion into the right subtree of the lef...

搜索二叉树(BinarySearchTree) 每一颗子树,左边比我小,右边比我大 搜索二叉树一定要说明以什么标准来排序 经典的搜索二叉树,树上没有重复的用来排序的key值 如果有重复节点的需求,可以在一个节点内部增加数据项 搜索二叉树查询key(查询某个key存在还是不存在) ...
最终结论,优化过的 avl 和 linux 的 rbtree 放在一起,avl真的和 rbtree 差不多,avl 也并不总需要回溯到根节点,虽然旋转次数多于 rbtree,但是 rbtree 保持平衡除了旋转外还有重新着色的操作,即便不旋转也在拼命的重新着色,且层数较高,1百万个节点的 rbtree 层数和 1千万个节点的 avl 相同。 所以查询,删除...

The balancing of the tree is not perfect but it is good enough to allow it to guarantee searching in O(log n) time, where n is the total number of elements in the tree. The insertion and deletion operations, along with the tree rearrangement and recoloring, are also performed in O(log...
